ad-ated to su ort and ide a cont ct levBe it known that I, WALTER. Wir-,I JIAMSI verplli whichpp gu a HORN, citizen of the United States, re lflhe end 15 of thel lever 14 which projects siding' at Shelby, in the county of Richland l inward toward the contact disksis bifurand .State of I0h10., have invented certain l cated and,l adapted to receive the circuit new and useful Improvements in ySignal i closer 16 which is yieldingly. secured therein Mechanism, of which the' following is a i l specification. y' I My invention relates to a signal mechanism which rings electric bellsy placed in dif- I ferentlocationsand its primary object is to i provide a means `of.ringing the electric'bell i dle 20. oi-.bells a pre-determined number of times to calla certain-person whosefcall corresponds bell rings.

i trical connection with the contact disks when il desired.

projects through an aperture 19 provided in with an arm or stud b secured to the` shaft 2 and l A further object is to provide means i by'preventing the rotation of the shaft 2.

whereby the call is automatically repeated? A plate 21 is secured to the exterior of the until the person responds t0 the call or the i operator moves the lever to off position at which time the signalmechanism will be.; automatically stopped.y and the signal cease. i

which is provided with notches 24 which are y placed opposite the disks and may be pro- It further consists in the combination and vided with a number corresponding to the arrangement of parts hereinafter described. z'

vI attain these and other objects .by the i oppositewhich it is placed. These notches form a means of retaining the circuit closer mechanism illustratedin the accompanying drawings in whichv 1 j Figure l is a front elevation of the device'- with a portion of thecase broken away showl ing the contact disks. Fig, Q'is a plan view ,l of Fig. 1. Fig. 3 is. an `end view in section and shows, the device connected to a bell. Fig. 4 is a detached viewof the contact lever i and a section of one of thecontact disks and, shows the position of the said parts when l the device is in operation. Y ln the drawings reference, numeral 1 represents the case or frame of the device having a shaft 9. mounted therein. The end 3 of saidshaft is journaled in a bearing secured in the case and the opposite end 4 of the connected to a type of motor shown by reference numeral 5 the purhandle 20. y pose of which will be hereinafter specified. inposition to' Contact with thedisk members A plurality of disks l6 are mounted on the and cause the pro-determined'signal lto. be shaft 2 and spaced apart by the sleeves 7 and lgiven ou the bell. lVhen the lever is moved are rigidly clamped to the shaft by means of laterally, the arm is released from'the arm the shoulder 8 and vthe threaded nut The. i disksl 6 have -contacts 10 grouped around their peripheries, the space or interval il i between'each group on the same disk being i equal. (See Fig. 3.) Each group on a disk i inafter described.

.Motion is transmitted from the spring motor (or other motor.) 5 to the shaft 2 by means ot the gear which meshes with apinion 2 6 secured on the shaft 2. 1When it is desired is pressed downward out of the range of the disk members and vmoved laterally along the bar or guide disk carrying the required signal members and released when the lever will drop by gravity into the" notch corresponding tothe pre-determined signal as the end l5 is "of rotate making and breaking the circuit and each time a disk member contacts with the circuit closer. I

Attention is called to the fact that when the operator moves the contact leverlaterally to the ynotch corresponding with the call given to a certain person .that-thebells lin must contain an equal number of contacts the purpose of which will be hereinafter de- A. bar 12 is secured to the inner wall of thc case by means of the brackets 13 and is is slidably mounted thereon.v

by a pin 1? and is adapted to make an'elec-l The opposite end 18 of the lever- 14,.

The operation of my device is as follows:

to send a predetermined.signal, the lever le allowing and causing the bell 25a to ringA the case and is fitted with anA insulated han' .-tn insulated member ais provided on the lever 14 and is adapted tohengage provides a means of stopping the motor number of contacts in a group on the disk in engagement with the desired disk -as herey 12 to the notch opposite the greater weicht than the end 18 and the b ,q

lhe circuit closer 1G will. thon be.

c and the shaft. 2 immediately begins to llO the different location will ringst-he pre-def termined signal until the person answers the call. The pre-determined signal will be given continually with an interval of time between them unless moved to off lposition by the operator or the lever moved to give a different call or signal.

The electrical connect-ions are as follows: Current is conducted from a battery by the wire 26a to the binding post 27 and to the motor 5 by the wire 28. The current flows through the motor and the shaft 2 to the disks l() and when -a contact is made with the circuit closer the current flows out through the arm 14 to the bar 12 and bracket 13a and through the wire 29 to the binding post 30. The bell 25CL is included in the Wiring between the .binding post 27 and the battery as shown in Fig. 3.

The disks will continue to rotate and repeatl the signals until the lever 14 is re turned to the position shown by full lines in Fig. 2 when the arm b will engage with the insulated 4lug a and the motor will be stopped as hereinbefore described.

A removable pin 31 is adapted to be inserted in suitable apertures in the winding posts 32 and provides a means for winding;h

the motor.

Having fully described my invention,

what I claim and desire to secure by Letters Patent is:

A signal device comprising a casing with a shaft mounted therein, ineans to rotate said shaftfineans to preventits rotation, a series of disks provided with contacts and mounted on said shaft, a bar, a lever slidably mounted on said bar, a contact closer pivotally secured to said lever, said contacts being mounted on the disks in series comprising different groups with any one of the series oi' contacts being adapted to contact' with the contact closer continually if desired, means to elec.- trically connect said 'contacts and closer, a signal device, and means to electrically connect said signal device to the contacts and Contact closer.

In testimony whereof l aiix my signature in presence of two witnesses.
